Wireless digital dental x-ray sensor with positioning apparatus

Abstract

A universal integrated wireless digital dental x-ray sensor and positioning apparatus includes a digital array sensor, such as CCD or CMOS, attached to a distal end of a bite block portion through a hinge assembly. Attached to an opposite end of the bite block portion is a housing. The housing houses the electrical components which includes the digital imaging processing unit, a wireless transmitting unit, a power source for operating the electronics and a coupling for recharging the power source. An on-board viewer may be in the housing. The electrical components are coupled to the sensor through wires embedded within the bite block portion and extending through the hinge assembly. A target x-ray member is attached to the tubular housing for proper direction of the x-rays onto the sensor.

Description

[0001]This application claims the benefit of provisional patent application Ser. No. 60 / 559,578, entitled “Wireless Digital Dental X-Ray Sensor with Positioning Apparatus” filed Apr. 5, 2004.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention relates to digital dental x-ray devices. Specifically, the invention relates to an integrated wireless digital dental x-ray sensor, optional on-board viewer and positioning apparatus.[0004]2. Background Information[0005]Dentists and oral surgeons have historically used light and x-radiation (“x-rays”) to obtain and then store images of their patients' teeth, mouths and gums to aid in diagnosis of a patient. In traditional oral and dental radiography, a cartridge containing a piece of radiographic film is placed in the patient's mouth, for example behind a patient's tooth, and an x-ray beam is projected through the tooth and onto the film. The film, after being exposed in this manner, is developed in a dark room or a cl...

AI Technical Summary

Benefits of technology

"The present invention is an integrated wireless digital dental x-ray sensor and positioning apparatus that addresses problems with conventional film and wired digital x-radiography. The apparatus includes a digital array sensor attached to a bite block through a hinge assembly, with electrical components and a target x-ray ring for proper direction of the x-rays onto the sensor. The apparatus also includes an eccentric offset pivoting connection for aligning the target in proper position and an articulation joint for angular positioning. An \"on-board\" viewer is integrated into the sensor and bite block elements, and a removable target alignment mechanism is attached to the housing for proper alignment of the X-ray machine relative to the sensor. The sensor and target are removable from the housing, and the housing may receive other components, such as an intra-oral camera. The technical effects of the present invention include improved accuracy and efficiency in dental X-ray imaging and improved patient comfort."

Problems solved by technology

Furthermore, in some situations the paralleling technique is not possible or practical.

The existing digital dental devices do not have adequate universal structure for proper positioning of the sensor within the patient's mouth, nor do they provide convenient location or housing of the digital imaging components.

Further, there is no existing digital dental device that provides viewing integrated with the sensor.
